Trusted Platform Module (TPM) technology is designed to provide hardware-based, security-related functions. A TPM chip is a secure crypto-processor that is designed to carry out cryptographic operations. The chip includes multiple physical security mechanisms to make it tamper-resistant, and malicious software is unable to tamper with the security functions of the TPM. Some of the key advantages of using TPM technology are that you can:
Generate, store, and limit the use of cryptographic keys.Use TPM technology for platform device authentication by using the TPM’s unique RSA key, which is burned into itself.Help ensure platform integrity by taking and storing security measurements.
The most common TPM functions are used for system integrity measurements and for key creation and use. Related read: Windows 10 doesn’t Start or Stops responding on Surface.
